To investigate the influence of sowing date on the phenology and grain yield responses of a core set of 36 wheat genotypes.
• Frost significantly influenced flowering date and grain yield in 2017.
• High grain yields can be achieved from a range of genotype × sowing date combinations.
• Whilst flowering time is important in maximising grain yield potential, timing pre-flowering phases was also found to significantly influence grain yield.
